Change PSO's language to Japanese, select "Download" when you connect to online mode, download the Sunset at the Secret Base quest, and play it offline (in Japanese). There are tutorials on GameFAQs and elsewhere detailing how to get the items. You can also download and use Garon's Scheme (in English), but you can't get the items from both quests on the same character and difficulty.
Have to give a big thanks to Bigboyzs! I have been playing online with him the last couple of days and he gave me his ChuChu mag!! Also, him and a couple of you guys have been a big help getting me leveled up. So thanks!!
